Every driver should know how to adjust the clutch on their car. This procedure must be carried out when the disc and clutch basket are changed, as well as when these elements are excessively worn. The movement of the car on the highway is almost always at a constant speed, gear shifting is very rare.

But when driving around the city, you have to constantly stop, slow down or increase speed, the clutch pedal is sometimes squeezed out several dozen times in one minute. In this case, significant wear occurs both in the drive mechanism and in the clutch elements.

Hydraulic drive

There are two types of drives that have become widespread in passenger vehicles. The first is hydraulic, which includes the working and master cylinders. They are connected by a flexible tube, which contains the brake fluid. The driver creates pressure in the system with the pedal, the master cylinder pistonmoves under the action of the stem inward.

On the working cylinder, the rod at the same time extends outward and acts on the clutch fork. In this case, the disc is disconnected from the working surface of the clutch basket, as a result of which the gearbox is disconnected from the engine. Such drive designs were widely used on VAZ cars of the classic series - models 2101-2107. It has a rather complicated design, the probability of breakdowns is much higher than that of a cable one.

Cable drive

The cable drive system of the clutch mechanism is very simple in design, there is practically nothing to break in it. At the base is a flexible cable that connects the clutch fork and the pedal. It is coated on the outside with silicone for maximum mobility.

Widely used on all VAZ vehicles, starting from model 2108. Before adjusting the clutch on a VAZ, you need to find out which drive is installed on the car. To do this, it is enough to know the model of your car.

Hydraulic Pedal Adjustment

In order to correct the position of the pedal, do the following:

1. There is an adjusting nut at the junction of the pedal and the master cylinder rod. It must be loosened in order to correct the position of the pedal.
2. Turn the nut to reduce clutch pedal freeplay.
3. Since you can still adjust the clutch pedalby adjusting the position of the rod on the working cylinder, it is desirable to do this as well.
4. Loosen the lock nut, then rotate the adjusting nut, achieving minimal free play. Allowable value is less than 160 mm.

All tuning is done empirically - the number of revolutions that need to be done to reduce free play may be different, it all depends on the condition of the car and its systems.

Please note that the expansion tank must be filled with fresh brake fluid, and clearly by level. Otherwise, the drive mechanism will not work.

Cable-type clutch adjustment

This drive is used on vehicles with front-wheel drive. These are "nines", "tens" and newer "Grants" and "Priors". A small instruction on how to properly adjust the clutch on cars with a similar drive:

1. Loosen the fixation of the cable on the bracket, which is located on the gearbox, using two keys to "17".
2. The outer nut must be unscrewed to increase the overall length of the cable.
3. Again, tuning is done empirically. We made a few turns - fixed the position with the second nut and checked the free play of the pedal.
4. If the free play has not decreased, then the adjustment procedure must be repeated.
5. At the end of all work, you need to tighten the inner nut well, put it in placerubber boot.

It is advisable to replace the cable in a timely manner, as it can break at the most inopportune moment. The outer nut must not be rotated when tightening - it is with its help that the length of the cable is adjusted.

Replacing the drive cable

Since it is unlikely to be possible to adjust the clutch with a worn drive cable, it is advisable to install a new element. Its cost in stores is about 250 rubles. But after the replacement, even the old "nine" will not be able to yield to any budget foreign car. The clutch pedal will be very light, which will improve the handling of the car.

To replace the cable, do the following:

1. Engage the speed on the gearbox and install wheel chocks under the rear wheels.
2. Remove the cable from the clutch fork.
3. Remove the two nuts to release the cable from the bracket.
4. Disconnect the cable from the bracket. There is nothing holding him back anymore.
5. Disconnect the second end of the cable from the pedal. To do this, remove the lock washer.

After that, you can completely remove the entire clutch drive and install a new one in its place in the reverse order. After installation, it is imperative to adjust the free play of the pedal. This will improve the handling of the car.
